WENDT CARD HOLDING ATTACHMENT FOR A TYPEWRITER OR LIKEPRINTING MACHINE Filed Feb. 26, 1957 2 Sheets-Sheet 2 INVENTOR FR RICKC. WEND 52a ATTORNEYS This invention relates re an attachment for aprintin Uniwd w j device and more particularly relates to aworkcardliold in'g assembly which may be" attached to' the carriageof atypewriter or like machine. The work card holding assembly is adapted toreceive and support relatively small sized cards, such as checks and thelike, in a desired print receiving position during the typingoperation.

Considerable difliculty is encountered when attempting totype a lineofprint on'short'stifi wor kcards. First, due to their rigidity, s iichca'rdsfresistconforming to the curved surface of the platen when beinginserted into the machine in the normal manner; This necessitates a timeconsuming manipulation of the work cards and i the paper feed contfollevers in order to" initially bring the work card to thedesiredprinting'positioh. Secondly, because that portion of thefwork card whichis to be printed on does not always lie flat against the operativesurface of the platen impact of the type bars' against said portion ofthecardisapt to'cut or rupturethe card material and/or smudge theprinted figures.

One object of the instant invention is to provide a Patented l2,

2 an inverted U-shaped profile andis'vert ica'lly adjustably secured byanysuitable' means to an elongated cross bar 5. The card receiving slot'formed by? said U-shaped member 1" is closed at its'left" endbyabentovei ear 6. Crossbar 5 may be appropriately olfsetor formed' as at7in order to accommodate the contour of the particular machine with whichthe card holding assembly is tojlie used; At the left end of crossbar 5therefisfsecuredf a headed stud 8 and at the"right end thereof there issecured a stud 9. A handle or finger piece 10 fastened to said bar 5provides a convenient means for manually adjusting and .positibni'n'gthe cardholhingmehibe 1 The arriage" supporting means" forth'e ca dtlomih assembly comprises a locking member 11', which is secured by' anysuitable" means to the leftxliand end of carriage frame 12 and whichisprdvidedl with a wedge shaped notch 13. At the right hand end ofthecarria'ge 14 there is provideda latch assembly 18, Fig. 3, comprisihgabase'plate l9 wliich'isfastened by any suitable means tothe'right side0t w'all' ztlof'carriage le andwhi'chis provided with a laterallydisposed ear 21 having apfin receiving hole 22. Pivotally mounted on thebase plate stud 24 is a manually operable latch" 25 having a forwardly"extendinghooked portion" 26. ILatch 25 isretained in its clockwiseorrelease position agaiiistbase plate stud 27 by means of a conventionaltype" b e'rcenter spring 29 which is operativelysecured between thelatch stud 30 and the base plate" Stud 31;

Ascale member 15 is secured to the carriage frame 12 b'yjmean s offastening screws'161 The mounted position ofsaidscalemember 1-5 is suchthat theupper edge 17 thereof is coextensive with thelower carh surface43 of" said notch 13. This arrangement facilitates the atrelativelysimple and inexpensive work cardsuppo'rting I assembly which may. beeasily attached to and-removed from a conventional typewriter carriagewhereby the necessity of rolling the'work card into the" carriage in theusualmanneriseliminated.

Another object ofthe invention is to provide a reliable means forsupporting smallworkcardsin a desired print receiving position wherebysaid cards may be quickly brought to and removed from said positionwithout attaching said cards to any'part of thetypewriter platen.

A further object of the invention is to providean eflicient means forretaining the print receivin portionof the work card in contact withtheoperative surface of the platen. l

Another object of the invention is to provide a simple means forsupporting thework card. so" thatrio relative horizontal movement occursbetween the work card and the platen during the typing operation.

Other objects will become apparent as the disclosure progresses.

. For a more detailed descriptiomofthe preferred emjbodiment of theinvention'referencehs made to the draw ings wherein:

Fig. 1 is a perspective view showing the card holding assembly and theprincipal parts of a conventional typewriter to which said assembly isto be attached.

Fig. 2 is a perspective view showing the card holding assembly in itssecured position on the typewriter carriage.

Fig. 3 is a side elevation in partial section showing the card holdingassembly operatively secured to the typewriter carriage.

Referring to Figs. 1 and 2, the card holding assembly comprises aU-shaped trough member 1 having a front wall 2 extending upwardly andterminating with an angularly disposed flange 3. The upper portion ofthe rear wall 4 of the said member 1 is rearwardly bent to tachment ofthe card holding assembly to" the typewriter carriage as will behereinafter described.

In order to press the print receiving portion of the work card againstthe forward surfaceof the platen32 there is provided a pair of spaced"horizontally extending guides 33 and 34, Fig. 2, which are fixedlysupported on the machine base by any suitable means and" whicharepositioned immediately adjacent the operativesurface 'oftheplaten.The outer ends of said guides 33 and 3'4 are bent over to respectivelyform the angularly disposed guide surfaces 35 and 36 which engage and"guide the headed stud 8 on the upper edge 17 of the scalememher 15 asshown in Fig. 1. Cross Bar 5' may then be moved to the left" bymeans ofhandle 10 until the said shaft portion of stud 8 rides intothe notch 13of locking member 11 as shown in Fig. 2. The cross bar stud 9 is thenaligned with and inserted into the hole 22 of base plate ear 21.Thereafter latch 25 is rotated counter clockwise from the releaseposition shown by the solid lines of Fig. 3 so that the hookedportion-26 thereof engages the forward face of the cross bar 5therebysecuring the card holding assembly to the carriage 14. Theover-center spring 29 assists in maintaining the latch 25 in the counterclockwise or locking position shown by the dotted lines of Fig. 3.

In the operation of the typewriter a work card 40 is inserted into theopen end 41 of said trough member 1 and is moved to the left betweensaid guides 33, 34 and the platen 32 until it engages the bent over ear6 at the left end of trough member 1 as shown in Fig. 2. The work card40 will then be horizontally and vertically positioned so that thesubsequently typed figures will be located on the desired areas of card40. The guides 33, 34 will insure that the print receiving portion ofthe work card is properly supported by platen 32 during thetypingoperation. When the typing operation has been completed the workcard 40 need only be moved to the right and withdrawn from the machinethrough the open end 41 of trough member 1. It will be seen that verylittle time and effort'is required to insert, position and withdraw eachsuccessive work card.

It will be 'noted in Figs. 2 and 3 that the .vertically disposed cardreceiving slot of trough member 1 is not I It is apparent that U-shapedtrough members having slots of varying depths may be provided in orderto accommodate either work cards of different sizes or work cards havingdifferently located print receiving areas.

While there is in this application specifically described one form whichthe invention may assume in practice, it will be understood that thisform of the same is shown for purposes of illustration only and that theinvention may be modified and embodied in various other forms withoutdeparting from its spirit or the scope of the appended claims.
